Installing a Level Probe 101

Level probe installation can be a tricky procedure. These probes often reach from the top to the bottom of the tank. With such a long, and heavy, sensor, just getting it into the tank requires thought and a little muscle.

Mounting Options

Understanding your mounting options is key. What openings are there on your tank or vessel? How big are they, and will a float pass through it? We have mounting options for just about any set-up you have, but getting the wrong mount can be a pain to fix.

Specific gravity of your liquid plays an important role here, believe it or not. The specific gravity of your liquid affects which float you can use on the probe, and how big or small it will be. All of this needs to be sorted out before your order your probe.

Mounting Position

Mounting position on the tank can affect the performance of your level probe. Specifically, if you’re mounting next to inflow or outflow, turbulence will increase – and bounce your float around.

There are a few things to consider if you’re worried about turbulence. First, securing the bottom of the probe may be required if the force of the flow is too great. Our level probes are built to handle a lot of abuse. However, like anything else, there is a point where the probe itself can bend. Securing the bottom will prevent this from happening, and ensure long lasting performance, even with very high turbulence.

Second, a stilling well might be appropriate. Stilling wells are pipes in which the level probe will rest. Holes in the top and the bottom ensure that the liquid rises and falls in the pipe along with the rest of the tank. This baffles turbulence, giving your probe a still environment.

Wiring Requirements

There are a few bases to cover with wiring. First, is this a hazardous environment? This requires running conduit and using seals. If not, what power source is available, and what sources of electrical noise do you need to avoid.

Our best recommendations are to use a good power source, avoid electrical noise, and use shielded cable. This will ensure the best possible result.

Special Equipment

Lastly, consider the height of the tank you’re dealing with, and the weight of the probe. Typically, weight isn’t a problem, even at 25 ft. However, if you have special ordered a particularly long probe, make sure you have enough hands to do the job right and keep everyone safe.

For tall tanks, a forklift, scissor lift, or cherry picker might be required. Take special precaution when using large equipment, and this increases the chance of an accident. A professional equipment operator knows that even seemingly harmless situations can turn dangerous with nothing more than carelessness.

Give us a ring if you have any questions about installing level probes. These sensors are accurate, reliable, and well built. They are workhorses; often the answer for harsh environments that other sensors just can’t handle.

Your installation will go smoothly if you’re thoughtful about all the variables. Planning ahead is the key. If you’re worried about forgetting about something, give us a call and we’ll ask all the right questions to make sure you’re ready to go.
